How to check the value of a varriable of a subfunction?

Suppose, I've a function called creating_learning_set.

function [Instances T_target]=create_learning_set()

srcFiles = dir('colored_textures\LearningSet\cloud\*.jpg'); % the folder in which ur images exists

Iin=[]; %this hold the data as input to the neural network

Target=[]; %this holds the target or the required result for each class %we put it manully. %read the folder containing the colud images

for i = 1 : length(srcFiles)

    filename = strcat('colored_textures\LearningSet\cloud\',srcFiles(i).name);
    I = imread(filename); %read the image
    F=get_image_features(I);
    .............
    .............
    (some lines are here)  
end

function [F]=get_image_features(Icolored) %% get R G B components of the sub-image

R = Icolored(:,:,1);

G = Icolored(:,:,2);

B = Icolored(:,:,3);

.......... ..........

(some lines are here. )

end

Now I want to checked the value of R from get_image_features(Icolored) after debugging. But it shows me an error that "Error in ==> get_image_features at 5 R = Icolored(:,:,1);"

How can I do it?

You can use the command line option

 dbstop if error

Or you can insert breakpoints inside your function to inspect (or change) the values at that point of the execution.
